APPARATUS AND METHOD FOR OPTIMIZING CONGESTION CONTROL INFORMATION IN A MULTI-PROTOCOL NETWORK

摘要

The benefits of Transport Control Protocol (TCP) over Available Bit Rate (AB R) Service of an Asynchronous Transfer Mode (ATM) network is extended to the entire TCP connection by intercepting and modifyi ng TCP congestion control information in accordance with resource information associated with the TCP connection. An algorithm calculates a new advertised window size based on various network resource parameters, such as ABR. The advertised window is adjusted if the newly calculated window size is smaller than the advertised window size. By adjusting the TCP window, the normal extreme fluctuations of the TCP window are avoided.
